SPLIT PU LLEY.

SPECIFICATION forming part of Letters Patent No. 390,102, datedSeptember 25, 1888.

Application tiled February 3, 1888. Serial No. 262,897. (No model.)

To all whom it may concern.-

Be it known that I, ADOLPH H. \VAGNER, of Milwaukee, in the county ofMilwaukee, and in the State of Wisconsin, have invented certain new anduseful Improvements in Split Pulleys; and I do hereby declare that thefollowing is a full, clear, and exact description thereof.

My invention relates to split pulleys; and it consists in certainpeculiarities of construction and combination otparts, to be hereinafterdescribed with reference to the accompanying drawings, and subsequentlyclaimed.

In the drawings, Figure 1 represents a side elevation of a pulleyconstructed according to my invention and partly broken away on line 11, Fig. 2; Fig. 2, a face view of the pulley, partly in section, on line2 2, Fig. l, and Fig. 3a transverse section on line 3 3, Fig. 1. Figs. 4and 5 are detail views of the meeting edges of the pulley-sections.

The rim of the pulley is made in the usual manner and then cut in two toform sections A B, the sides of said rim being finished with a bead, G,that hides the cuts and increases the width of face. Half-round recessesE are cut in the meeting ends of the rim sections, and when thesesections are together said recesses form circular openings for dowelpinsF, the latter being shown as permanently secured by transverse pins ornails P, as shown in Figs. 1, 2, and 5, in the recesses of the rimsection B.

\Vhile I have shown thehalf-round recesses E and circular pins F, it isobvious that said recesses and pins may be angular,if found moredesirable, the purpose of the pins being to pre vent lateraldisplacement of the sections A B that form the rim of the pulley.

Mortised in each rim-section of the pulley are the ends ofatransversebracepiece, G, said rim-section and brace-piece being keyedtogether by dowel-pins II that are shown as circular, butwhich may be ofany other desirable form.

Passed through the bracepicces of the opposing pulley-sections are rodsI, and on the ends of these rods are arranged clamping-nuts J.

Each of the brace-pieces G is centrally recessed to engage a square hub,K, the latter being preferably made in two sections for the sake ofconvenience, and held in place by the pressure of said brace-pieces. Thehub K being detachable from the pulley, any-sized shaft can beaccommodated without the employment of bushings, as it is only necessaryto know the diameter of said shaft in order to furnish a hub having acorrespoudingly-proportioned here, it being intended that all hubs shallbe of a standard size as regards outside measurement, and differ only asto the diameter of bore.

By the construction above described I pro vide a simple, easilyconstructed, and durable split pulley that has no liability to get outof shape or run loose on the shaft to which it may be connected.

I am aware that heretofore split pulleys have been made with removablehub-sections interposed between the arms thereof.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- 1. A split pulley having themeetingedgcs of its sections recessed, and dowel-pins fitted into theopenings formed by the recesses and secured by transverse pins passingthrough said dowel-pins and into one of said sections, substantially asset forth.

2. A split pulley having its rim-sections A. B recessed at their meetingends, dowel-pins fitted into the openings formed by the recesses andseen red by transverse pi us passing through said dowel-pins and intoone of said sections, the transverse brace-pieces G, mortised anddoweled in the rim-sections, the hub K, detachably fitted between thebrace-pieces, the rods I, and clamping-nuts J, substantially as setforth.

In testimony that I claim the foregoing I have hereunto set my hand, atMilwaukee, in the county of Milwaukee and State of Visconsin, in thepresence of two witnesses.

ADOLPH H. WAGNER.
